Topic: NOS idler arm

Found this on eBay - not mine.

Any comments as to whether or not this is appropriate for a manual steering Mustang application?  The part number does not show up in the 65-72 MPC.

Looks the part to me . Here is another one with the more recognizable service sticker. http://www.ebay.com/itm/NOS-1967-70-Mustang-Boss-302-IDLER-ARM-C7ZZ-3350-B-MINT-CONDITION/251747924562

C9AZ-3350-A shows up in a Master Parts Catalog I have on a page dated December, 1969. It's listed as 69/up car line A (full size Ford, like Galaxie). I don't know what the difference is, but it's not listed for a Mustang with that part number. The "final edition" MPC that many people have describes a different part number (D3AZ-3355-A) for the full-sized Fords.

The difference is how far the arm is pressed on to the bushing . Same dimensional part as on the Mustang but it is pressed on differently. On Mustang version it is pressed on and  basically centered on the bushing. The one in the auction is pressed to one end. I suppose this changes the steering relation for the larger car. The C7 Mustang power steering idler arm has the same similarities with the larger car with the exception of where it is pressed onto the bushing . Different engineering number put same physical parts as the Mustang version. To make it work on a Mustang you only have to center the arm on the bushing . Some creative press techniques and you have the same thing as the Mustang. to understand better what I am trying to explain you can see the different position when you compare the first picture link to the second picture link. The Mustang arm will sometimes have a C7 engineering number on the arm portion and sometimes not .Maybe different supplier.

Question: I understand the difference between the pictures in both listings, Thank you Bob for pointing this out. (asside of pricing of course  ) But I am confused about the applications that are in the listings.

1st, that the one John (67gta289) has the link to, can be made to fit a 67-70 Mustang and a Boss (by centering the bushing in a press) but makes no mention of with or without power steering.
2nd, the one at Perkins is listed as fitting ALL 67-70 Mustangs AND Boss 302 with MANUAL STEERING.

Are both of these parts ONLY for cars without power steering? Or do they also fit cars WITH power steering, but not on certain models. I have no MPC to look up such things.

Thanks, Richard

Don't have my books open but believe the first one (C9AZ-3350-A) and the second (C7ZZ-3350-B)

Both arms are typically for manual steering applications easy to tell by the hole in the chassis side bracket. 67-70 manual steering arms typically had the hole . Powersteering arms did not. The arms between the powersteering and manual steering are very close visually. I do not know the significance of the hole .It is above my pay grade . Someone else more versed in the complexities of the engineering differences between manual and powersteering will have to explain the different relationships on the arms.  FYI David Davis made me aware that there is a very small fractional difference in length between the Torino application and the Mustang which you can't tell without measuring closely . Visually they look the same . I think you would be splitting hairs trying to tell the difference in appearance and performance on a given car.
